Continuous corn is the most common irrigated crop sequence in southwest Nebraska. Although rotating to other crops, such as soybeans, can mitigate some production issues of continuous corn and often boost the next year’s corn yield, larger adoption of soybeans has not readily occurred in this area.
Public universities and private companies were contacted early in 2019 to provide input on the study protocol that would compare multiple fertility programs for soybeans in western NE. A total of 12 fertility programs were compared.
Yellow field peas (Pisum sativum L.) recently gained popularity across Nebraska due to their rotational benefits and increase in consumers' demand for plant-based alternatives to meat and dairy products.
In southwest Nebraska, irrigating corn and soybeans with limited water is challenging due to typically dry weather conditions and high crop water use (i.e., evapotranspiration or ET) in July and August.
Research in southwest Nebraska looks at potential water savings from adding field peas and chickpeas in corn-soybean rotations where irrigation water is limited. Both pea crops efficiently used early-season precipitation for good yields.
When integrating field peas into a crop rotation, herbicide carryover is one of the most important things to consider. This guide can help you plan your herbicide program to avoid potential crop injury due to carryover injury.
